Blood in the ventricle that is destined for the pulmonary capillary beds is in contact with the:
a. right ventricular myocardium
b. the aortic valve.
c. endothelial cells of the endocardium.
d. epithelial cells of the pericardium.
e. connective tissue cells of the pulmonary valve.

The correct answer will be option C- endothelial cells of the endocardium.

Explanation:

The pulmonary capillary bed is the network of capillaries in the lungs- alveolar region mainly where gaseous exchange takes place.

This bed receives blood from the pulmonary arteriole which arises from the pulmonary artery. The blood is pumped to this artery through the right ventricle of the heart. The right ventricle- especially the valves is lined from with the endocardium which lines it and prevents the blood from sticking to the inside of the chamber.

Therefore, the blood pumped from the right ventricle is in contact with the endothelial cells of the endocardium and option C is the correct answer.

answer: the answer is d.

explanation: this is because when you exercise you make your muscle produce a certain liquid, that does not evaporate it.   also when you exercise you do not reduce muscle fiber.   and it does not really control your twitch that much.
